They finally agree on something.

Representatives of both the Trump and Clinton campaigns pushed back Wednesday on claims made by Facebook CEO Mark Zuckerberg that his company warned them about Russian hackers.

Zuckerberg attempted to clarify his meaning as he told lawmakers during his heated testimony before the House that he meant the social media behemoth tipped off the RNC and the DNC, not the campaigns of the candidates.

A day earlier the billionaire mogul told Senators that both campaigns were warned during the 2016 election that cyberattacks were originating from Russia.

"One of my greatest regrets in running the company is that we were slow in identifying the Russian information operations in 2016. We expected them to do a number of more traditional cyberattacks, which we did identify and notify the campaigns that they were trying to hack into them," he said.

Robby Mook, former campaign manager for the 2016 Hillary Clinton presidential campaign, said the claim was "not true."

"We were never notified. I hope Zuckerberg and Facebook correct the record," he tweeted.

Brad Parscale, who was the digital director for the Trump campaign, shared a similar sentiment.

"Funny to say this, I completely agree with @RobbyMook on this one," he wrote on Twitter. "I wasn't told about this. @facebook needs to get their stories straight."

U.S. intelligence is confident that Russia used hacking and fake news to interfere in the 2016 presidential election.

The Kremlin orchestrated the hacking of the Democratic National Committee and other political organizations and released of thousands of stolen emails, many of which included damaging revelations about former Secretary of State Hillary Clinton, the party's nominee.

Facebook shot back at Mook's comments in a tweet of their own late Tuesday.

"We contacted the DNC and RNC during this time to protect the accounts of key employees and to work together to spot potential additional malicious activity. We also were in contact with the FBI," said Facebook chief security officer Alex Stamos replied.

Zuckerberg also revealed that Facebook was exploring whether to take action against the University of Cambridge.

The institution is where researcher Aleksandr Kogan, who had collected and sold personal data to Cambridge Analytica, was based.

Cambridge Analytica harvested the personal data of millions of Facebook users and was hired by the Trump campaign to target voters during the 2016 contest.

"What we found now is that there's a whole program associated with Cambridge University where ... there were a number of other researchers building similar apps," Zuckerberg said. "So, we do need to understand whether there was something bad going on at Cambridge University overall that will require a stronger reaction from us."

The university balked at Zuckerberg's claim, saying it would be "surprised" if he was only now aware of their work.

"Our researchers have been publishing such research since 2013 in major peer-reviewed scientific journals, and these studies have been reported widely in international media," the school said in a statement.
